hey guys and gals,
I have a 1974 landcruiser with a chevy based 6 cylinder engine and a 2 barrel carb.
hope you guys can help with this carb. this carb. has a primary and secondary jet and my question is which takes the jet with the larger jet size.at present it is also using the 2 larger jets in the carb. and keeping as spare jets the 2 smaller jets within the carb. jet plugs. so which is the larger jet , the primary or secondary, and down here in south texas, which set of jets would be best, the larger os the smaller.
thanks for all your help
